SIP User's Manual 6. Configuration Parameters Reference
6.16.2 Fax and Modem Parameters
The fax and modem parameters are described in the table below.
Table 6-54: Fax and Modem Parameters
Parameter Description
Web: Fax Transport Mode
EMS: Transport Mode
[FaxTransportMode]
Fax transport mode used by the device.
 [0] Disable = transparent mode.
 [1] T.38 Relay = (default).
 [2] Bypass.
 [3] Events Only.
Note: This parameter is overridden by the parameter
IsFaxUsed. If the parameter IsFaxUsed is set to 1 (T.38
Relay) or 3 (Fax Fallback), then FaxTransportMode is always
set to 1 (T.38 relay).
Web: Fax Relay Enhanced
Redundancy Depth
EMS: Enhanced Relay Redundancy
Depth
[FaxRelayEnhancedRedundancy
Depth]
Number of times that control packets are retransmitted when
using the T.38 standard.
The valid range is 0 to 4. The default value is 2.
Web: Fax Relay Redundancy Depth
EMS: Relay Redundancy Depth
[FaxRelayRedundancyDepth]
Number of times that each fax relay payload is retransmitted
to the network.
 [0] = No redundancy (default).
 [1] = One packet redundancy.
 [2] = Two packet redundancy.
Note: This parameter is applicable only to non-V.21 packets.
Web: Fax Relay Max Rate (bps)
EMS: Relay Max Rate
[FaxRelayMaxRate]
Maximum rate (in bps), at which fax relay messages are
transmitted (outgoing calls).
 [0] 2400 = 2.4 kbps.
 [1] 4800 = 4.8 kbps.
 [2] 7200 = 7.2 kbps.
 [3] 9600 = 9.6 kbps.
 [4] 12000 = 12.0 kbps.
 [5] 14400 = 14.4 kbps (default).
Note: The rate is negotiated between the sides (i.e., the
device adapts to the capabilities of the remote side).
Web: Fax Relay ECM Enable
EMS: Relay ECM Enable
[FaxRelayECMEnable]
Determines whether the Error Correction Mode (ECM) mode
is used during fax relay.
 [0] Disable = ECM mode is not used during fax relay.
 [1] Enable = ECM mode is used during fax relay (default).
Web: Fax/Modem Bypass Coder
Type
EMS: Coder Type
[FaxModemBypassCoderType]
Coder used by the device when performing fax/modem
bypass. Usually, high-bit-rate coders such as G.711 should be
used.
 [0] G.711Alaw= G.711 A-law 64 (default).
 [1] G.711Mulaw = G.711 μ-law.
